Application of Synchrotron Radiation Techniques for Model Validation of Advanced Structural Materials

Manuel Alexandre Pouchon, Wolfgang Hoffelner, Maria Samaras

Synchrotron radiation techniques represent powerful tools to characterize materials down to the nanometer level. This paper presents a survey of the state-of-the-art synchrotron-based techniques which are particularly well-suited for investigating material ...

Determination of the single-ion anisotropy energy in a S=5/2 kagome antiferromagnet using x-ray absorption spectroscopy

Henrik Moodysson Rønnow, Goran Nilsen

We report x-ray absorption and x-ray linear dichroism measurements at the Fe L-2,L-3 edges of the geometrically frustrated systems of potassium and hydronium iron jarosite. Comparison with simulated spectra, involving ligand-field multiplet calculations mo ...

Kinetic hard-modelling and spectral validation of rank-deficient spectroscopic data: a case study

Julien Léo Billeter, Konrad Hungerbühler

In this case study, we apply a recently developed method to systematically predict the linear dependencies in concentration profiles and identify minimum requirements to enable optimisation of rate constants and pure component spectra via direct multivaria ...

Harmonic holographic microscopy with circularly polarized excitation

Demetri Psaltis, Ye Pu, Rachel Grange, Chia-Lung Hsieh

We have developed a luminescent marker using the second harmonic generation (SHG) from noncentrosymmetric BaTiO3 nanocrystals. These nanoparticles are attractive due to their stable, non-saturating and coherent signal with a femtosecond-scale response time ...

Analysis of transient mechanical loss due to thermal stresses in metal matrix composites

Daniele Mari, Robert Schaller, Abu Salek Md. Fahim Chowdhury

Mechanical spectroscopy has been used to study the thermal stress relaxation at the interfaces in magnesium matrix composites. The mechanical loss spectra measured as a function of temperature show an intrinsic component superimposed on transient damping. ...

Functional electric field changes in photoactivated proteins revealed by ultrafast Stark spectroscopy of the Trp residues

Majed Chergui, Frank van Mourik, Andrea Cannizzo, Erwin Portuondo Campa, Stefan Haacke

Ultrafast transient absorption spectroscopy of wild-type bacteriorhodopsin (WT bR) and 2 tryptophan mutants (W86F and W182F) is performed with visible light excitation (pump) and UV probe. The aim is to investigate the photoinduced change in the charge dis ...

Nonfouling Polypeptide Brushes via Surface-initiated Polymerization of N-epsilon-oligo(ethylene glycol)succinate-L-lysine N-carboxyanhydride

Jian Wang, Harm-Anton Klok, Matthew Gibson, Raphaël Barbey

This contribution describes the preparation of nonfouling polypeptide brushes via surface-initiated ring-opening polymerization of oligo(ethylene glycol) modified L-lysine N-carboxyanhydrides. Circular dichroism experiments indicated that these surface-anc ...

Polarization Issues with High Power Injection and Low Power Emission in Fusion Experiments

Timothy Goodman, Federico Alberto Alfredo Felici

All tokamak experiments using ECCD require setting of the beam elliptical polarization for proper coupling to the plasma. This is done either in the matching optics unit (MOU) at the output of the gyrotron, or in a couple of miter bends of the transmission ...
